Hi rgpejm4fqui2,
I'm sorry to hear you've run into this trouble after returning to Plants vs. Zombies 2. I completely understand how disheartening it must be to find you can't access an old account that you put so much time into.
Progress that was once saved directly to a Google Play account is now managed through a linked EA Account. Your old progress is likely safe, but it is tied to an EA Account that needs to be recovered.
For your account's security, we can't access your details or recover accounts here on the forums. However, our support team can help. To do this, the most critical piece of information you can provide is your original Player ID.
Please review our guide on how to find your Player ID. Even if you can't log in, it provides tips on where else you might have saved it:

If you have ever made any in-game purchases, receipts from your Google Play history are also excellent proof of ownership that can help the team find your account.
Once you have gathered any information you can find, please contact our support team. They are the only ones who can investigate and help you recover your old account. You can submit a ticket using the direct webform.
When you contact them, please explain that you are a returning player, that the Google Play login is gone, and provide them with your old Player ID if you found it.
I truly hope the team can help you get your progress back.
